"China has "vastly increased" the risk of a nuclear accident by opting for cheap technology that will be 100 years old by the time dozens of its reactors reach the end of their lifespans, according to diplomatic cables from the US embassy in Beijing.

The warning comes just weeks after the government in Beijing resumed its ambitious nuclear expansion programme, that was temporarily halted for safety inspections in the wake of the meltdown of three reactors in Fukushima, Japan."
